I always make it a point to delete the computer cache and history I've used when ever I logged in an internet cafe, because some internet cafes are not using a deepfreeze software, so the computer always remember your history and your prints, but I'm glad I'm not going into the cafe since I have a laptop and netbook around
This is very good option because I am also doing this for some long time as one of my friend has some serious problems due to this password reminder mostly I try to avoid public computers because of security but sometime if I have to use then must try to delete all things after use.
